Specification of Letters Patent.

Patented Apr. a, 1918.

Application filed June 21, 1917. Serial No. 176,117.

To all whom it may concern:

Be it known that I, JOHN WV. FAESSLER, a citizen of the United States, residing at Moberly, in the county of Randolph and State of Missouri, have invented. certain new and useful Improvements in Locking Devices for Awning-Gearing; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to roller awnings and more particularly to gearing for actuating the take-up roller of an awning of a type which is supported wholly from the top or lintel of a window as distinguished from those having column support, the principal object 'of the invention being to eliminate the usual operating box and connecting rod and effect the location of all of the operating as well as supporting mechanism above the window.

The invention is particularly adapted and serviceable for fronts lacking column or other supportingbases but adaptable and desirable for any building front in that it obviates the location of any of the awning mechanism at a level that would detract from the appearance of the building and form an i obstruction to pedestrians.

In accomplishing the object of the invention, I have provided improved details of structure, the preferred forms of which are illustrated in the accompanying drawings, wherein:

Figure I 1s a perspectlve view of a roller awning of a lateral arm type, equipped with any improved take-up or actuating gearlng.

Fig. II is an enlarged, detail, perspective view of the gearing, particularly illustrating the locking bracket within which the actuating shank of thegearing is seated to hold the roller. 1

Fig. III is an elevation of parts of the gearing and a part of the take-uproller with its awning, portions of the gearing being in section for better illustration.

Fig. IVis an end view of the gearing, showing the locking shank in locked position in dotted lines and inoperative posit pei' 'ii l i s- 4 ally mounted on said pin Fig. V is a perspective view'of the preferred form of actuating crank.

Referring more in detail to the drawings:

1 designates an awning roller ofany ordinary type, having bearing pins 2 at its ends rotatably mounted in bearings 3 on brackets 4: which are secured to a building front or lintel 5 above the window space which the awning is intended to protect or shade, the bracket as well as the awning structure bemg of any ordinary type and mounted in the usual manner, as these parts in themselves form no part of the present invention except in so far as they are combined with the improved gearing mechanism hereinafter described. r p

The awning proper comprises the canvas or other top 7 attached at its inner edge to the roller 1 and at its outer edge to arod Sin the usual manner, the rod 8 being connected with the front of the building by spreading and supporting mechanism of any ordinary type, here shown to consist of lateral arms 9, the inner members. 10 of which are pivoted to the front of the buildin on the vertical axes 11 and the outer D members 12. of which are pivotally connected with the ends of theinner members 10 and pivotally connected'with the rod 8. With this construction the lateral rods pivot at their inner and intermediate hinge points to fold" andilie against the front of the building, but are adapted, when the awning is released, to movement of the awning and stretch the awning as disclosed, it being apparent that the weight of the arms, the rod 8 and the awning material is sufficient to automatically extend the awning when the roller is released.

Fixed on one of the end pins 2 of the roller 1 is a bevel gear wheel 14, and pivotis a housing band 15, preferably of triangular shape with its base 16 at the outer end of the frame and extend under the outward the apex at the inner end thereof; the apex I the frame, is a shaft'19 having a' squared shank 20;at its free end adapted for' fitting snugly Within a socket 21 in a horizontal arm 22-..of a strip 23 which is attachedto the front of the building,,preferablythrough the base of the bracket 1; the mouth of said socket, being flared in order that the squared shank may readily find its seat therein when moved toward the front of the building. Fixed to the shaft 19 within the skeleton frame 15, preferably by a cross pin 24, is a bevel pinion 2 5 which meshes with the bevel gear Wheel 14% so that when the shank 1s rotated as presently described, the pinion is revolved to rotate the awning roller 1, the pinion having a hub 26 bearing against the inner face of the housing base 16 to hold the shaft against longitudinal displacement from the housing.

As the awning will automatically extend, unless locked against such movement, it is essential that the actuating shank 19 be retained within its locking socket except when the roller is being operated and to insure such location I connect the skeleton frame 15 with the roller bracket l by a coil spring 25, having suflicient strength to automatically seat the gearing shank within its socket and retain the same'in position, but which will yield to permit the shank to be removed when the awning roller is to be actuated.

As a convenient means for actuating the roller I provide a crank 27, comprising the rod 28 having a squared socket 29 in one end adapted for receiving the squared end of the shank 19 of the roller gearing and having a handle member 30 at its opposite end, a sleeve 31 being loosely mounted on the rod 28 adjacent the handle and held in position against longitudinal movement thereon by the pins 32, so that the operator may grasp the collar with one hand and turn the rod with the other to manipulate the gearing.

Assuming that an awning of the character described is equipped with my improved 7 gearing, the operation for extending and taking up the awning isas follows:

When the awning is up the material is wound on the roller 1 with the rod 8 above the building front and the lateral arms 9 folded thereagainst. WVhen the awning is to be let down the operator projects the squared socket on the end of the actuating crank over the end of the gearing shank 20 and swings the crank to remove theshaft from the locking arm 22. He then grasps the sleeve 31 with one hand and turns the handle 30 contra-clockwise with the other to allow the awning to unfold or unroll. As the awningunfolds or unrolls the lateral arm members 10-12 turn on their axes toward their extended position and if the awning is allowed to be lowered to its com plete limit the armsare straightened nearly to a point of alinement, the relation of the width of the awning to the length of the arms being such, however, that complete alinement is not possible, thereby obviating any tendency of the arms to hold against take-up movement of the awning.

When the awning has reached the desired extension the operator brings thecrank back toward the front of the building and thereby positions the squared shank 20 of the gearing shaft 19 within the socket 21 of the locking arm to hold the gearing against further actuation and retain the awning in posibly interfere with pedestrians, and making possible the use of awnings on buildings to which it would be impossible to attach an awning by another type of mounting.

Having thus described my invention, what I claim as new therein and desire to secure by Letters-Patent, is:

1. A roller comprising a fixed gear mem- 1 her, a mounting rotatable on the roller, a

gear member rotatable in said mountingjin mesh with the fixed gear member, a shaft connected with the rotatable gear member and adapted for operative connection with an actuating device, and alocking device adapted for receiving the shaft to holdthe roller in adjusted position.

2. A roller comprising a fixed lgear member, a mounting'rotatable on the roller, a gear member rotatable in saidmounting in mesh with the fixed gear member, a shaft connected-with the rotatable gear member and having a squared shank, and a locking member having a squared socket for receiving said shank.

3. A roller comprising a fixed gearmember, a gear member cooperative with the fixed member to actuate the roller and movable to and from a locking position, means for locking said movable gear member to retain the roller in adjusted position, and means for yieldingly urging the movable gear member to locking position.

4. A roller comprisingan actuating and supporting axle, a bevel gear wheel fixed on said axle, a housing revolubly mounted on said axle and comprising alining cup and journal bearings, a shaft journaled in said bearings and having a squared free end, a pinion fixed on said shaft to retain the-shaft in its bearings and mesh with the fixed gear wheel, a fixed arm having'a squared socket for receiving the squared portion of'said shaft, and a spring connected with said housing to urge the shaft to its locking seat.

5. A roller comprising an actuating and supporting axle, a bevel gear wheel fixed on said axle, a triangular housing having col- 1 30 lars at its apex revolubly mounted on said axle, nal hearings in its apex and base respectively, a shaft journaled in said bearings and 5 havin a squared free end, a pinion fixed on said 5 aft to retain the shaft in its bearings and mesh with the fixed gear wheel,

and comprising alining cup and joura fixed arm having a squared socket for receiving the squared portion of said shaft, and a spring connected with said housing to 10 urge the shaft to its locking seat.

In testimony whereof I atfix my signature.
